Isicelo:

I-Potassium Dichromate (CAS: 7778-50-9) ine-oxidation enamandla kanye nokugqwala, futhi ingaxutshwa ne-ejenti enciphisayo, izinto eziphilayo, izinto ezivuthayo noma impushana yensimbi ukuze yakhe ingxube eqhumayo, engabangela ukuvutha noma ukuqhuma ngokungqubuzana, ukudlidliza noma umthelela. .
I-Potassium Dichromate, iyabola ukuze ikhulule umoya-mpilo ekushiseni okumhlophe, ine-oxidation eqinile, iyi-oxidizing eqinile enobuthi ne-carcinogenic.Ihlukaniswa njengeqembu I-carcinogen yi-International Agency for Research on Cancer (IARC) futhi ingase ibambe umlilo lapho ichayeke ezintweni ezivuthayo.Ngenxa yokuthi i-Potassium Dichromate inezindawo eziqinile zokuhlanganisa i-oxidizing ngaphansi kwezimo ezine-acidic, ivame ukusetshenziswa elabhorethri ukulungisa isisombululo sokugeza i-chromic acid (ingxube ye-saturated potassium dichromate solution kanye ne-concentrated sulfuric acid) ukugeza i-glassware yamakhemikhali ukususa ukungcola okunciphisa ezindongeni isitsha.Ngemuva kokusetshenziswa, ukugcoba kuyashintsha kusuka kokubomvu okumnyama kuya kokuluhlaza, futhi ukugcoba ngeke kusebenze.I-Potassium dichromate ibuye isetshenziswe kukhemikhali yokuhlaziya, evame ukusetshenziselwa ukunqunywa komthamo we-reductive hydrogen sulfuric acid, i-sulfurous acid, i-ion ion nokunye.Ekushiseni, i-potassium dichromate ingaphinda ifake i-hydrochloric acid egxilile, ukukhululwa kwe-chlorine.
Isetshenziswa ekukhiqizeni i-chrome alum, i-Chromium Oxide Green, umbala ophuzi we-chrome, i-electrode, uyinki wokuphrinta, nayo isetshenziswa njenge-ejenti yokushuka, umbala woqweqwe lwawo, ukuphrinta kanye ne-Dyeing mordant esetshenziswa ekukhiqizeni i-chrome alum, i-chrome oxide eluhlaza, i-chrome yellow pigment.Imboni ye-enamel nempushana yayo ende, isihlabathi se-quartz kanye nezinye izimpushana zoqweqwe lwakwa-calcined, njengombala oluhlaza.Ukulungiswa komentshisi Inhloko Yemithi, kusukela endimeni ye-oxidation kanye nomswakama.Isetshenziswa njenge-ejenti yokushukwa kwesikhumba esikhanyayo.Ukudaya kwe-Mordant nokuphrinta kusetshenziswa njenge-mordant.Amakha okwenziwa alungiselelwa ukusetshenziswa njengama-oxidants.Isetshenziselwa i-welding electrode, inki yokunyathelisa, i-metal passivation.Isetshenziswa njengama-oxidants kanye nama-catalysts ku-organic synthesis kanye nezinto zokusetshenziswa kwezemithi.
Isetshenziswa ekwenzeni amakhemikhali e-chromium, i-mordant, inki, ingilazi, amakha, i-pigment, i-ceramics, i-varnish, iziqhumane, imithi, njll.
Isetshenziswa njenge-oxidant, i-potassium chrome alum kanye nereferensi yokulungiswa kwama-reagents amakhemikhali
ukulinganiswa kwezixazululo ezijwayelekile ze-sodium thiosulfate.Ukuhlaziywa kokulahla kwe-chlorine, ama-oxidants, ama-Chromatography Reagents, i-organic synthesis.Ukusebenza kwesibindi kanye nenkomba ye-gallbladder kukalwa.Indle, njll.
Isetshenziswa njengereferensi yereferensi, i-redox titrant, i-chromatography reagent kanye ne-oxidant, nayo isetshenziswa ku-organic synthesis.

7778-50-9 - Ukuphepha:

Igundane lomlomo LD o:190mg/kg.I-Chromium iwumthombo ozwelayo, futhi i-chromium ene-hexavalent iyacasuka futhi idle.Ngemuva kokuhogela kungase kubonakale ukuvuvukala kokuphefumula, isifuba somoya, izilonda ze-chromium.Iyacasula kakhulu esikhumbeni.I-IARC carcinogenicity Ukubuyekeza umdlavuza womuntu kubhalwe kahle.Le nto ingase ibe yingozi emvelweni, futhi ukunaka okukhethekile kufanele kukhokhwe emzimbeni wamanzi.Abasebenzi kufanele bavikelwe kahle, uma bethinta amehlo ngephutha, kufanele bahlanza ngokushesha ngamanzi amaningi agelezayo.Indawo yokusebenza kufanele ibe nezimo ezinhle zokungenisa umoya.Gcina endaweni epholile, eyomile, isitsha kufanele sivalwe ukuvimbela umswakama.Gwema ukugcinwa ndawonye nokuthutha ngezinto eziphilayo, izinto ezivuthayo, izinto ezinciphisayo, ama-oxide nama-asidi.

Isitoreji Nezimpawu Zokuthutha:

Indawo yokugcina impahla ingena umoya futhi yomiswe ekushiseni okuphansi;Ilula futhi kulula ukuyikhipha;Ihlanganiswe nezinto eziphilayo, i-reductant, isulfure ne-phosphorus izinto ezivuthayo, isitoreji esihlukile sezinto zokusetshenziswa zokudla.
